Oscar Mendez

I graduated from the University of California, Irvine in 2012 and worked in the lab of Aileen Anderson before joining the Neuroscience program at the University of Arizona in 2014. I joined the Koshy lab in spring 2015.

Research Interests

Neurodevelopment, Regeneration, Axon guidance

Research Summary

My graduate project entails defining the regions of the brain that are most susceptible to Toxoplasma infection, the neuron subtypes that are targeted by Toxoplasma, and how Toxoplasma effector proteins alter neuron physiology in vivo
